Application tiled April 28, 1899. Serial No. 714,806. (No model.)

To a/ZZ when?, it 77u01/ concern:

Be it known that I, JOHN LJUNG, a citizen of the United States, residingvat Nelson, in the county of Douglas and State of Minnesota, haveinvented a new and useful Nailing-Machine, of which the followingisaspecication. I

This invention relates to nailing-machines, the object being to providea simple and efficient apparatus of this character which is adapted tocarry a large supply of nails to be furnished for use as required,thereby avoiding the necessity of placing them in the mouth or in thepockets, and the nails can be readily fed one by one with rapidity totheproper point, and bya use of the machine the workman is enabled towear gloves or mittens in cold weather, and while the machine isprimarily adapted for furnishing nails to be used in fastening shinglesto roofs and other structures it is apparent that it can be employedwith equal advantage in many different arts.

The device includes in its construction nailsupply means and a devicefor carrying a nail bodily from the same to a position Where it may bestruck by a hammer, hatchet, or like implement, and the nail-supplymeans consists, preferably, of a trough or magazine inclined at theproper degree and a runway communicating with the chute and along whichthe nails may be pushed by hand and a carrier which is adapted totransfer the. nails bodily from the runway for use as re quired, andthis carrier may be of any suit able construction and operated in anyconvenient manner. ln other wo`rds, the nail carrier or separator gripsthe individual nail and moves the same to a position isolated from theother mechanism, and thereby provides for holding the nail in a positionreadily accessible for hand-nailing.

W'ith these ends in view the invention consists in the novel combinationof elements and in the construction and arrangement of parts, which willbe hereinafter fully described and claimed.

To enable others to understand the invention, I have illustrated thepreferred embodiment thereof in the accompanying drawings, forming apart of this specification, and in which- Figure lis a side elevation ofa nailingmachine constructed in accordance with my invention. Fig. 2 isa plan view of the machine. Fig. 3 is a rear elevation. Fig. 4. is adetail in perspective of the delivery end of the runway for the nails.Fig. 5 is a detail plan view of the magazinechute- Fig. C is a detailcross-sectional view on the line 6 G of Fig. 5. Fig. 7 is a detail inperspective of the magazine-ch nte. Fig. Sis a detail in perspective ofthe actuating-lever for reciprocating the nailcarrier. Fig. 9 is adetail sectional view on the line 9 9 of Fig. 2, showing more plainlythe arrangement of the supporting device for the magazine-chute. Fig. 10is a detail sectional View on the line l0 10 of Fig. 2, showing therelative arrangement of the upper and lower guiding-springs associatedwith the reciprocating nail-carrier.

Like characters denote like and corresponding parts in each of theseveral iigures of the drawings.

The nailing-machine is intended principally for furnishing nails for usein shingling, and it is transportable, preferably, and should be mountedupon a truck or framing, which latter may be of any suitableconstruction.

The truck represented is denoted by T, and it consists of two side bars2, joined at the front and rear by the cross-pieces 3, these partsusually being made of strap-iron and the cross-pieces having upturnedends to support the axles et and et' of t-he truck, which are providedat their ends with Wheels 5, adapted to roll upon a roof or other placeas the apparatus is shifted f`rom point to point.

The nail-supplying mechanism includes in its construction an inclinedmagazine trough or chute (i, having a slot 7 throughout its length,through which the shanks or bodies of the nails project, and providedwith upturned vertical side walls b' and'closed at its upper end, as at9. This inclined chute or trough 6 is provided with the nail-receptaclel0, disposed substantially in a horizontal position and constitutingwith the chute the nail-magazine and having a closed end l2, in thecenter of which the vertical slot 13 is formed, the upper end of theslot being widened, as at 13, and the hole being shaped to agree withthe `form in longitudinal section of the nail, which is passedtherethrough and is advanced toward the na-ilpcarrier or picker to beconducted by the latter to the point of IOO use. The nail-receptacle 10has a longitudinal slot 14, forming a continuation or prolongation ofthe longitudinal slot 7 in the chute, and the vertical walls 15 risefrom the bottom of the nail-receptacle at opposite sides of said slot 14and merge on curved lines into the inclined bottom of the chute anddivide the nailreceptacle into two compartments or chambers. Thenailspass along the slot 7 and then between the vertical walls 15, theirheads being supported by the upper edges of said walls, and they aresuccessively pushed through the T-shaped slot 13 and from thence passinto a runway, from which they are taken by the nail-picker.

The nail-runway, to which reference has been made, is denoted by R, andit consists of two substantially similar or duplicate side pieces orstrips 16, one of which is secured to the upturned ends 17 of the sidebars 2, while Y the other of which is secured to thevertical strips orbearings 1S, which in turn are secured to said npturned portions 17, andthe respective parts are spread or spaced apart above the upper edge ofthe side pieces 16, thereby to permit the free movement of the heads ofthe nails which rest upon the runway. The innermostvertical member 18extends upward higher than its companion and is connected to thediagonal brace 19, which in turn is fastened to the adjacent side bar 2near the front axle et, thereby strengthening the structure. Thevertical upright 1S, to which I have just referred, serves to uphold thelocking-standard 20, to which a connection joined to the chute 6 isunited.

The inner closed end wall 12 of the nailreceptacle 10 is provided on theouter side thereof and at the opposite sides of the vertical slot 13therein with the oppositely-arranged pairs of inclined retaining-flanges21, forming therebetween recesses 21 to receive the cooperating wing'sor flanges 22, fitted, respectively, to opposite sides of the runway Rat the inner end thereof, said wings 22 being upwardly convergent, so asto register in the recesses between the retainingflanges 21, and therebyproviding a rigid detachable joint or connection between the contiguousends of the magazine-chiite and said runway, whereby the slots of therunway and of the magazine-chiite will remain in precise alinement, soas to form directcontinuations,`

and thereby permit of the free travel of the nails from the magazine andupon the runway to thefdischarging end of the latter.

The standard 20, to which I have hereinbefore alluded, is verticallydisposed for the major part of its length and terminates at its lowerend in the transverse extension or foot 23, provided at its end with ahook 24, adapted to engage the bail 25 near its middle, and said bailhas eyes or openings 26 at its inturned ends to receive the transverserod 27, supported by the ears 2S on the nail-receptacle 10. The lowerend of the standard 20, near its transverse extension 23, its againstthe projection or cross-piece 29, which con nects the parts 17 and 1S,and it is bent inward and forward near its upper end to forma loop 30,which partially embraces or straddles the part 1S. The said standard isprojected upward beyond this loop 30 and is provided with a second andsubstantially U-shaped bend, the upper branch 31 of which is materiallylonger than its companion and constitutes the head of the standard andreceives the loop or eye 32 at the bend, of the angular connecting-piece33, one end of said connecting-piece being coiled to receive the stirrup34, located at a convenient point in the height of the chute 6. Theshorter leg of the connecting-piece is provided with a hook 35, adaptedto engage in an opening in the upright 1S.

From the foregoing it will be understood that the member or part 18constitutes a rigid upright support for the magazine-chute, and at thispoint it is to be observed that the loop 30 of the locking-standard' 2Ois sprung into engagement with one edge of the supportingupright 1S,whereby the locking-standard will exert a leverage upon the cross-pin29, with the latter as a fulcrum, and cause the engaging hook 2-1 toexert a strain upon the bail 25, and thus insure the rigid positioningof the lower end of the magazine-chute, while the connecting piece orwire 33 by reason of its engagement with the upper branch 31 of thelocking-standard and also with the supporting-upright 18, as plainlyshown in Fig. 3 of the drawings, provides for properly bracing the maininclined portion of the chute. Furthermore, the parts referred to areseparably associated together, whereby the magazine-chute may be readilydetached from the remainder of the machine or swung to 31.

To load the machine, it is properly grasped and a handful ot' nails areput into the nail receptacle or box 10 when the device is in its normalposition, after which the latter is tilted, allowing the nails to slideslowly toward the top of the trough, at which point the nails aremomentarily held and slowly freed, so that they may escape in scatteredorder and run down the trough and pass into the elongated slot 7 untilthe heads of said nails strike the bottom of the trough. The nails canthen pass from the trough between the vertical walls 15, and to preventtheir jumping out the stop or arresting device 26a is disposed in theirpath and is preferably carried by the upper end of the wall 12 upon theinside thereof and consists of a resilient or spring finger adapted tobe struck by the foremost of the nails and which permits the nails topass between the opposing' sections of the runway R, the nails beingsuccessively taken from the delivery end of the latter and bodilyconveyed therefrom for, use as occasion demands.

The uprights 37 are secured to the two side pieces 1G of the runwayextending upward therefrom and being spread apart near said IOO IIO

runway sufficiently as to permit the free progress of the nail-heads,and the U -shaped bar 38 is secured to these strips and also to theouter uprights 18 and extends downward and rotatively supports the axle39, provided with the guide-wheel 40.

The nail-carrier is denoted by N, and it is reciprocated across thedischarge end of the runway transversely thereof and is of such aconstruction as to pick Ithe nails singly from the runway and advancethem to aplace beyond the same, where they may be driven home by ahatchet or like implement, and as each nail is required the machine willbe moved forward to repeat the operation.

The nail-carrier N has two lingers 4l and 42, respectively, the workingends of which are in proximity and which are made sufficiently resilientor springy to assure them obtaining a firm hold upon the nails, and saidnail-carrier is provided with a slide-loop 423, which embraces andslides upon the guiderods 44, projecting in parallelism from the outerside piece 16 of the runway, said rods constituting a convenient supportfor the nailcarrier.

The runway has a recess or notch 45,through which the inner branch orfinger 4l of the nail-carrier N reciprocates, and said branch has nearits end the cut-away portion 46, between which and the adjacent finger42 the nails are singly received and conducted forward on the workingstroke of the nail-picker. By cutting away the inner finger 41, as juststated, a thin springy extension is provided upon the same. The nailsare pushed along the runway and the foremost one will abut against theouter finger 42 when the said carrier is in its retracted position, andwhen the carrier is moved forward the reduced end of the finger willselect the foremost nail from the series and will press the same againstthe outer inger, so that when said carrier or picker is advanced thenail thus held will be moved away from the runway. The terminal portionof the nger 42 facing the portion 46 of the nger 4l is provided with anailengaging notch 46, which assists in holding the nail between thecontiguous ends of the fingers until the machine has advanced.

Associated with the reciprocating nail-carrier 9 is a pair of upper andlower guidingsprings 65 and 6G, respectively. The upper guiding-spring65 is coiled upon one of the guide-rods 44, as at 67, and has one endthereof fastened to a fixed part of the framework, as at 68, therebyleaving its other end free to exert a spring-pressure upon thenail-carrier N. The said upper guiding-spring 65 is arched over theguide-support for the nailcatcher and has the free terminal thereofdepend between the separate fingers or bran ches 4l and 42 of thecarrier, and normally the pendent free end of the guiding-spring 65bears against the spring stop plate or projection 69, which is projectedfrom the outer side ot' one of the guide-rods 44. The lower ot saidguiding-springs GG is also coiled, as at '70, upon one of the guide-rods44 and is secured fast at one end to a fixed part of the framework,thereby leaving its other end free to exert a spring-pressure againstthe nailcarrier. The main arm of said lower guidespring G6 is archedbeneath the guide-supports of the nail-carrier and is normally arrested'against one of the guide-rods 44, as plainly shown in detail Fig. lO ofthe drawings, and the free terminal of said lower guiding-spring 6G isextended beyond the contiguous guide-rod 44, against which it rests, andis disposed directly beneath the nail-carrier N to prevent downwarddisplacement thereof, while at the same time leaving the nail-carriersuiiiciently loose to insure the engagement thereof with a nail in amanner to be hereinafter fully explained.

lVith reference to the action of the upper guiding-spring 65 it will benoted that the stop plate or projection 69 keeps the spring normally outof engagement with the nailcarrier, especially at the moment the carrierengages the nail and swings the same laterally and outward from thecontiguous end of the runway R. When this occurs, the nail-carrierpresses outwardly against the pendent free end of the spring 65, and thelatter will therefore move the nail-carrier back again to its normalposition, so that the nail between the contiguous ends of the fingersthereof will be carried alongside of the longitudinally-disposed guard71, arranged at one side of the truck-frame. Saidlongitudinally-disposed guard 7l is provided with a pendent foot portionT2 beyond the discharging end of the runway R, which foot portionconstitutes a nail-carrier rest, against which the gripping end of thenail-carrier is thrown as it advances to a position to carry the nailcontiguous to the angular ham mer-guide 73, formed in the body of theguard 7l adjacent to the rest-foot 72. At this point it will be observedthat the inner finger or branch 4l of the nail-carrier is provided witha deected portion 4l, which rides against the pendent end of the spring65 and causes the advance end of the nailcarrier to be thrown alongsideof the rest-foot 7 2, as indicated in dotted lines in Fig. 2 of thedrawings. NVhen the nail has been carried adjacent to the angularhammer-guide 73, the same can be grasped and driven by the hammerwithout the latter interfering with any part of the machine. It is to beobserved that the hammer-guide 73 provides a clearance-space for Ithehead of the hammer in the hand of the operator and permits the nailbeing moved by the carrier to a position isolated from all other workingparts of the machine, whereby itis readily accessible forhand-nailing.In this connection it will also be noted that when the nail has beenadvanced by the nail-carrierto this isolated position the nail may bestarted while held by the carrier and then after a slight advancement ofthe machine-truck the guide IOO IIO

73 will permit the hammer to clear the adjacent parts of the machinewithout moving the same laterally. The said longitudinally-arrangedguard 7l is further provided with a horizontal guide extension 74,arranged in substantial parallelism to one of the guiderods 44 andconstituting a part of the guidesupport for the slide-loop 43 of thereciprocating nail-carrier.

.Any convenient means may be employed for reciprocating thenail-carrier, but for this purpose the actuating-lever 47 is preferable,said lever being manually controlled and be ing disposed within easyreach of the workman.

The lever 47, like the nail pi'ckeror carrier N, is preferably made ofwire bent to the proper shape, and it has at one end the transversejournal portion 4S, supported for oscillation by the bracket 49, securedat one end to the frame 50, and said bracket is also formed of Wire andhas a series of coils to receive the journal or pivot extension 4S. Thelever extends beyond the fulcrum and is located beneath the longitudinalhorizontal member of the frame and is provided at its end with alongitudinal loop 5l to slidingly receive the projection at the end ofthe crank 52 on the shaft 53, which is supported by the bracket 54 onthe inner end of the frame 50, and said shaft is provided with a secondcrank-arm 55, coiled at its end to receive the projection at the end ofthe link 56.

The link or pitman 56, connected with one arm of the crank-shaft 53, isprovided at the end opposite such connection with an elongated loop 75,which looselyT engages one end of the slide-loop 43 to provide for thereciprocation of the nail-carrier. The said elongated loop also embracesacontiguous end of an auxiliary starting-head 76, which transfers theinitial movement from the link or pitman 56 to the slide-loop 43. Thesaid starting-head 76 is in the form of a cross-head and is slidablymounted upon the rods 44 alongside of the loop 43, and at one end thesaid starting-head 76 is provided with a stop-arm extension 77, which isadapted to strike against the fixed abutment 7S, iitted to theguide-rods 44 and projected beyond one of said rods to lie in the pathof movement of the said stop-arms 77. The function of the auxiliarystarting-head 76 is to prevent movement being transferred to theslide-loop 43 of the nail-carrier until the nailhas been firmly engagedin the notch between the contiguous ends of the nail-carrier iingers.nection it will be observed that when the operating-lever 47 is elevatedto provide for actuating the crank-shaft 53 the motion from the link orpitman 56 is first imparted to the end of the auxiliarystarting-head,with which it engages. This end of the starting-head willbe drawn against the contiguous end of the slide-loop 43, andconsequently impart a slight rocking movement to this loop, so as tothrow the nail-carrier outwardly a sufficient In this con'.

distance to remove the nail from the contiguous end of the runway, afterwhich the nailcarricr advances and is returned to a normal position bythe pressure of the guiding-spring 65, as previously explained.

When the operating-lever 47 is lowered, the nail-carrier is drawn backto its initial position, ready to engage with and carry forward anotherindividual nail.

As already pointed out, the operating-lever is grasped by the workman,and the supporting-frame 50 thereof constitutes a convenient handle, aswell as assists in maintaining the operator in his position upon a roof,and the said operating-lever is preferably formed of stout wire bentinto proper shape and having parallel separate grasp portions 57 and thelower pendent loop 5S, between which the iingers can be thrust whilemanipulating the lever. The said operatinglever 47 is also provided withan upstanding stop-iingcr 59, adapted to engage beneath the upperhorizontal portion of the frame 50 to arrest the upward movement of thelever.

From the foregoing it is thought that the construction, operation, andmany advantages of the herein-described shingle-nailing machine will bereadily understood by those skilled in the art without furtherdescription, and it will also be understood that various changes in theform, proportion, size', and the minor details of construction Withinthe scope of the appended claims may be resorted to Without departingfrom the principle or sacrificing any of the advantages of thisinvention.
